Application filed July 12, 1913. Serial No. 778,760.

To all 'whom it ma/ concern l Be it known ti t and WILLIAM S. HoLnnooK, cltlzens of the United States, residing at Davenport, in the` andhas special reference to the dust receiving pan or drawer which may be readily removed and cleaned. 4

Anothen object ofthe invention is the production of a 'simple and efficient means for detachably supporting the dust bag section through. the rear end of the dust receiving drawer showing the manner in which the drawer is closed in the rear end thereof.

By referring to the drawings it will be seen that 1 designates the base ofthe cleaner which base carries at its forward end a suction block 2. This suction block 2 carries a metallic cover3 upon the lower face thercof, so as to produce a smooth surface along the entire lower face of the suction block 2. An aperture t is formed within the block 2 and this aperture fl communicates with an aperture 5 which aperture constitutes a port for allowing thevdust to pass from the apern ture 4L into the dust bag (3. A felt lining 7 is placed upon the inner face of the block 2 and the metallic collar 8 is secured to the inner :face of the block 2 which coll-ar conf stitutes a means for connecting the body 9 oi the drawer to the' block 2.

The body portion 9 of the drawer coniprises a metallic body having a wire mesh top 10 through which a suction may be obat we, NELSON M. Dran.'-

Fig. 6 is an enlargedtained bymeansof the bellows 11, to be hereinafter described. .The body 9 of the drawer lits snugly over the collar 8., as shown in Fig. 3, and it may, therefore, be seen that'the body may be readily removed from the collar when it is desired to remove the dust bug G from the dust drawer. The body 1 is provided with longitudinally extending rib portions 12 upon the inner face thereof, and the body portion 9 of the drawer is pro- 'vided` upon each side with a ledge portion 13 which ledge portion 13 fits under the ribs 12, the ribs 12 constituting a guide-way for the dust drawer.

A door 14 is hingedly secured to the rear of the dust drawer and is normally held in a closed position by means of the locking spring 15 and the overhanging flange 16 of the door 14. Springs 17 are secured to thev rear of the door 14 and engage the rear end of the body l so asto yieldably hold the door 14 in closed position upon the body 9 of the dust receiving drawer. s

The fabric bag 6 which is formed of the same shape as the body portion 9 of the drawer is placed within the drawer' and the forward end of the bag is drawn over the forward end of the body of the drawer and the collar 8 is forced in the forward end of the bag so asto firmly clamp the forward end of the bag between the inner face of the body portion 9 of the drawer and the outer face of the collar 8 of the block 2, thereby firmly holding the fabric bag G in engagement with the body portion 9 of the drawer without the aid of tacks or other permanent securing means. The opposite end of the bag 6 is then brought together and folded over the lower edge of the body portion 9 of the drawer, as clearly illustrated in Fig. 3, whereby the bag will be firmly held in engagement with the body portion 9 of the drawer and the escape of dust from the bag will in this manner be prevented. Of course, it should be understood that the bag 6 is readily removable from the drawer so as to permit the dust to be easily and quickl removed :lrorn the dust drawer especial y in view of the fact that no permanent securing means 'for holding the bag in engagement with the body portion 9 of the drawer has away from vthe apertures 22 to and these leather closure strips 28 are notl permanently secured around their entire edge, but are only secured suliciently to hold thegsame normally over the apertures 22. These closure strips 28 may be drawn permit the passage of air therethrough.

The rear end of the body 1 carries a plurality of brackets 24 upon which brackets 24: is journaled a Crank-shaft 25 to which crank-shaft are connected the bellows operi body l and by swinging the rod 33 upwardly ating links 26. Arms 27 .are secured to the upper boards 18 of the bellows 11 and are in turn secured to the respective links 2G whereby the bellows inay be operated as the shaft is rotated. Supporting wheels 28 are carried by the shaft 25 and the easing 29 is placed over the upper end of the base l to shield the bellows 1l.

The block 2 carries a plurality of spring members 30 upon the front end thereof and these spring members SO are provided with bulged portions 3l, which bulged portions are adapted to be engaged by the rubber collai's 32 of the locking rod This locking rod 33 has its ends pivotally secured within the journal plates 2554, which plates are secured to the body l. The looking-rod by engaging the springs 8O will firmly hold the drawer in its correct position within the the drawer inay be readily drawn therethrough.

A handle 35 engages the securing plates 3G carried by the body l for the purpose of facilitating the operation of the sweeper.

Frein the foregoing vdescription it 'will be seen that an air-tight dust and dirti'etaining removable drawer has been produced whereby the contents of the drawer may be dumped without spilling and also without soiling the hands,

Of course, it should be understood that the roeaeie invention maybe modified as to its detail mechanism and construction without departing from the spirit of the invention.

What is Claimed, is:

l. A Vacuum cleaner comprising a body, a removable drawer, a dirt retaining sack being open atboth ends, said dirt retaining sack removably mounted in` said drawer, and common means for closing one end of said sack and holding the saine in said drawer.

2.
